Active Recombinant Bovine TNF Protein

• Cat.No.: TNF-20B
• Product Overview: Recombinant Bovine TNF-alpha (78-234aa, 158aa) without tag was expressed in E. coli and purified by using conventional chromatography techniques.

Specification

• Species: Bovine
• Source: E.coli
• Protein Length: 78-234
• Description: Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation (By similarity).
  
  Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance.
